Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for joining irregularly shaped parts in press molding of parts.

An object of the present invention is to perform press molding of different shapes using one press die by simple and quick switching, thereby improving work efficiency and reducing equipment costs.

In press forming of sheet metal, there are cases in which press forming is required to have almost the same overall shape but a partially different shape.

In such cases, a plurality of press machines are each equipped with press dies of different shapes, and a meeting is carried out using the plurality of press machines. Therefore, it is necessary to carry in and out the workpieces for each press machine, which not only adversely affects work efficiency but also causes undesirable problems such as increased equipment costs and equipment space for the machine. SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems, the present invention provides a meeting device for press forming different shapes within one press mold.

Embodiments of the present invention will be described below with reference to the drawings. 1 is an upper die holder, and 2 is a lower die holder.

The upper mold die holder 1 is provided with an upper mold, an upper mold positioning device, a clamp device, etc. having the following configuration. That is, 3 is an upper mold, which is rotatably provided around a shaft 4. A first mold surface 5a and a second mold surface 5b having irregular shapes are formed on two right-angled surfaces, and a chevron-shaped first positioning protrusion 6a is formed on the surface opposite to the first mold surface 5a. ,
Further, a second positioning protrusion 6b is formed on the surface opposite to the second mold surface 5b. A positioning member/member 7 having a recess 7a in contact with the second positioning protrusions 6a, 6b is suspended by a bolt 8 so as to be vertically movable.

Further, a cam member 9 is slidably provided on the upper surface of the positioning member 7 and is in contact with the cam member 9, and is provided so as to be moved forward and backward by an operating rod 11 and a cylinder 12.

The contact surfaces between the cam member 9 and the positioning member 7 include a cam surface that presses the positioning member 7 at the forward movement end of the cam member 9, and a cam surface that allows the positioning member 7 to freely move up and down at the backward movement end. is formed. In addition, a shaft 4 integrated with the upper die 3
A handle 10 is fixed at the end.

Incidentally, instead of the handle 10, it is also possible to use an automatic rotation device using a rack and pinion mechanism operated by a cylinder. On the other hand, a lower die 14 facing the upper die 3 is installed in the lower die holder 2 so as to be horizontally slidable.

On the plane of the upper surface of this lower mold 14, there are a first mold surface 15a corresponding to the first mold surface 5a of the upper mold 3, and a second mold surface 5b.
A corresponding second mold surface 15b is formed. 16
is a cylinder for slidingly positioning the lower mold 14.

It is also possible to arrange the upper mold 3 and the lower mold 14 upside down, contrary to the illustrated example.

In addition, 17 in Fig. 1 is a hole punch, and the bolt 1
A holding body 18 is suspended by 9 so as to be movable up and down.
A cam member 2 that is fixed to the
When no drilling is required due to 0, it is in a free state,
It is attached to the device of the present invention so that it can be clamped when drilling is required.

A die 22 corresponds to the hole punch 17.

Next, the operation of the present invention will be explained.

The illustration shows a case where press molding is performed using the first mold surfaces 5a and 15a. This is the case. If press molding is now required using the second die surfaces 5b and 15b, the cylinder 12 is operated in the raised position of the upper die holder 1, and the cam member 9 is moved backward (second (moved to the left in the figure)
do. As a result, the clamping operation of the positioning member 7 is released, and the positioning member 7 becomes free to move upward via the bolt 8. In this state, the upper mold 3 is rotatable by the shaft 4, and is rotated 90 degrees counterclockwise in FIG. Upper mold 3-9
When rotated by 0°, the second mold surface 5b is located on the lower surface and the second positioning protrusion 6b is located on the upper surface, and the positioning member 7 is pressed by moving the cam member 9 forward by the operation of the cylinder 12. The recessed portion 7a abuts on the second positioning protrusion 6b to position and simultaneously clamp the upper mold 3. 5 Simultaneously with the rotational positioning of the upper die 3, the lower die 14 on the lower die holder 2 side is also moved forward in the right direction in FIG. The second mold surface 15b of the lower mold 14 is moved to the press working position.

The limit 13 is activated at the forward movement end of the lower die 14 to confirm completion of the switching change. Therefore, by moving the upper die holder 1 downward, the sheet metal on the lower die holder 2 is moved to the second position.
Press molding of different shapes is performed using the mold surfaces 5b and 15b. As mentioned above, the first mold surface 5a, 1
5a or the second mold surface 5b, 15b, holes can be simultaneously punched at predetermined locations using the attached hole punch 17, and if unnecessary, the hole punching can be disabled. It is also possible to do this. As described above, according to the apparatus of the present invention, in a press mold in which different types of mold surfaces are formed at different positions on the same plane and a lower mold that is movable and positionable is provided at a position facing the upper mold, the lower mold A mold surface corresponding to each mold surface is formed at a plurality of positions, and a chevron-shaped positioning protrusion for positioning each mold surface is formed on a rotatable upper mold, and the positioning protrusion engages with the mold surface. Since it has a chevron-shaped recess and is provided with a positioning member that is pressed and clamped in the engagement direction by a cam member, the rotational index positioning of the upper mold can be easily and reliably achieved, and the lowering movement of the upper mold This has the advantage that the upper mold does not undergo rotational displacement due to reaction force during press pressurization, ensuring a positioned position, and performing steady press molding.
